Abstract

This research discusses the design of a piezoelectric raindrop energy harvesting system integrated into a building's roof surface. The primary objective of the research is to convert the kinetic energy of raindrops into electrical energy by utilizing the piezoelectric effect, while simultaneously designing efficient material and structural configurations that are resistant to dynamic loads. The methodology used refers to the VDI 2221 systematic engineering approach, encompassing requirements identification, concept design, material selection, numerical simulation, and prototype fabrication and testing. The piezoelectric materials used are PVDF and PZT, installed under a polycarbonate roof layer with a rectifier system and energy storage capacitors. Test results show that the system is capable of generating voltage and electrical power proportional to rainfall intensity, with maximum voltage distribution occurring in the central area of the piezoelectric plate. This research demonstrates the potential of utilizing raindrop energy as a renewable energy source and supports innovation in environmentally friendly smart roof designs.

Abstract

The increasing demand for energy encourages the development of renewable energy sources, but the utilization of rain energy in Indonesia is still limited. This literature study examines the effect of rainfall intensity and water droplet size on the electrical output of polycarbonate piezoelectrics. The intensity variation is set at less than 5 mm/hour (light rain), 5-20 mm/hour (moderate rain) and 20-50 mm/hour (heavy rain), with droplet sizes of 2.5 mm, 5 mm, and 7.5 mm. The experimental method in this study was carried out by comparing the differences in rainfall intensity and the size of raindrops that fell on the roof that had been installed with a piezoelectric. The raw data measured were voltage and electric current. The results of data processing are in the form of piezoelectric performance, namely electrical power and efficiency. A review of the variations in rainfall intensity and raindrop size shows a relationship between the kinetic energy of the droplets and the piezoelectric output voltage.

Abstract

Raindrops hitting the roof material and the falling rainwater exerting pressure on the roof can be utilized as a power source with piezoelectrics as a converter of mechanical energy into electrical energy. The purpose of this research is to find the right roof material to produce maximum electrical power and efficiency in harvesting the energy of falling rainwater. This research method is carried out by comparing three types of roof materials placed on top of the piezoelectric. The falling rainwater will press the roof material and piezoelectric, thus producing electricity in the form of voltage and current measured with a multitester. The measurement data is processed into electrical power and efficiency. The results of the study found that the type of roof material affects the performance of the piezoelectric as an energy converter.
